to the shoe or detached therefrom, with the use of a simple tool, in such a manner that no straps or the like will be required for securing the skate. A further object of this invention is to provide such a fastening device which is highly efficient in its operation, easy to use, and economical to produce.

Further objects and advantages of this invention will be more clearly understood from the following description and from the accompanying Fig. l is an elevational side view of a skate fastened to a shoe with my improved fastening means.

Fig. '7 is a plan view of a modified form of a fastening device embodying my invention.

Fig. 8 is a side view thereof, partly in central vertical section.

7 As shown in the drawings, the numeral 5 denotes a skate, preferably an ice skate, which is "detachably secured to a shoe 6 by my improved fastening means.

The fastening means are preferably mounted on the heel supporting portion 1 and the sole supporting portion 8, which portions may be incorporated in a single plate extending along the top of the skate, or may consist of separate plates as shown.

Each of my improved fastening devices preferably comprise a stationary clamping member 9 which is secured to the supporting plate of the skate, by such means as rivets l0, and extends through an opening II in said plate as clearly illustrated in Fig. 5 of the drawings.

A movable clamping member I2 is slidably supported in a bracket I3 which is secured to the sup- 7 Claims. (01. zen-11.32)

porting plate, by such means as rivets H, and

has a groove l 5-in the top thereof which receives the movable clamping member [2 and slidably supports :said member under the supporting plate.

A clamp-operating rocking lever I6 is pivotally :mounted within a, slot I! in the supporting bracket l3 by means of a shaft 18, and a screw [9 is threaded to a tail portion 20 of the said rocker lever and engages the bottom 2| of the slot l The said screw I9 is provided with a suitable head to receive a wrench or key for rotating the screw to operate the fastening device. 7 V

The shoe is provided, both at the sole and the heel, -with suitable members, such as the disks 22 and 23, to receive the clamping members of the fastening device. Each of these disks is firmly secured toxtheir respective portion of the shoe by means of rivets 24, such as shown in Fig. 5, where the said disk 22 is shown secured to the heel 25. The said disks are preferably fitted within a corresponding recess in the shoe so that they are flush with the bottom surface of the shoe at the .for receiving the ends of the clamping members 9 and I2 as clearly illustrated in Fig. 5 of the drawings. I In the preferred form of my fastening device, the disks 22 and 23 are provided with opposite notches, as at 28 and 29, which register with the recesses 26 and 21. These notches are preferably curved, and the clamping members 9 and 12 are also correspondingly curved so as to set within the said notches and prevent longitudinal movement of the skate relatively to the shoe.

In the form illustrated in Figs. 7 to 9, the disk 30 is provided with an unbroken circumferential surface and the clamping members, such as the member [2a shown in Fig. 8, are correspondingly curved so as to embrace a portion of the circumference andnot onlyprevent movement of the disk crosswise to the clamping members, but also to secure the skate on the shoe against relative longitudinal movement.

In the operation of my improved fastening means, as illustrated in Figs. 1 to 6, theskate is placed upon the shoe with the clamping members 9 and 'I2 fitting into the recesses 26 and 21' in the heel of the shoe and 26a and 21a in the sole opthe shoe. The screw is is then rotated so as to push against the bottom 2| of the slot I! and rock the upper portion 20a of the lever 16 inwardly against the slidable clamp l2 and force said clamping member against the edge of the disk 22, thus clamping the said disk firmly between the clamping members 9 and I2 and firmly securing the skate to the shoe against lateral and longitudinal relative movement.

When it is desired to remove the skate from the shoe, the member i9 is simply turned in the opposite direction and the rocker lever will permit the clamping member l2 to become loosened and thereby readily released from the disk 22. It will be clearly understood from the above description that by the provision of the notches 28 and 29, in the sides of the disk 22, and the convex clamping surface on the members'il and I2, the fastening member is automatically located with its axis extending across the longitudinal axis of the disk 22, when mounted'on the shoe, and will thereby prevent movement of *the skate relative to the shoe. Also, in the form "illustrated in Figs. '7 to 9, wherein the clamping member isprovided with a concave inner surface,

the-clamping disk will be received 'on-the axis or the clamping members so that longitudinal movement of the skate relative to the shoe is also prevented.

In the forms illustrated in said Figs. '7 009, the "movable clamping member [2a is operated by means of a screw '3! which is threaded to the bracket 32 and has a flange 33 and a wrench receiving head 34. A washer 35 is preferably {provided between the flange 33 and the clamping "member [2 to relieve friction, and thesaid Washer "may be provided with a retaining prong 36 which extends over the edge of the flange 33'so as to retain the said washer upon the'sha'nk 31' of the screw. In this form, when the screw 3| is rotated for clamping operation of my fastening device, the flange 33, through the washer '35,

will force the slidable clamping member 12 a 'against the disk 30 and thereby clamp-said disk firmly-as above described.

It is pointed out that by forming the clamping members either with concave or convex shape,

as'illustrated, they may 'be constructe'd of sheet metal and reinforced by such-formation so'a-s to prevent bending thereof under the clamping 'pressure applied to them in the use of my improved fastening means.

It will also be noted that all of the mechanism comprised in the said fastening means is so constructed as to provide of'the sole and heel are notched atdiametrically opposite sides of the keeper disks-to 'pr'ovide clearance for clamping members of the fastening device; said device including a stationary cl'an'ip- 'ing member projecting upwardly through an opening'in said plate, amovable'clamp'ing member also projecting upwardly throughan'opening in said plate, both of said clan'iping members being engageable with marginal'edges of the keeper disk at said notched-portions, a bracket secured to the underside of said-plate and'slid- "ably supporting said movable'clamping member,

a rocker lever pivotally carried by said'bracket, and a screw through said lever for-forcing the movable clamping member into clamping positlon. I
